.WATEBFHEATERH To all whom `t may contara:

Be itv knownthat I, Ln'riamn'rC.' RHEA, a

.citizenof the United States, residing at Columbus, inthe county of Franklin and State invention not being coniined to the precise details of construction particularly depicted In said drawings: Figure isa. vertical section. and `Fig. 2 a horizontal section on the line Fig. 1. l f In the views 3 designates a suitable base from which is erected a tubular standard 4 having lateral openings 5, 'and an"e xter Vnally threaded upper end .6.

The character 7 designates a hollow sphere of suitablemetal having a tubular boss 8 threaded internally to be connected with the upper end of the tubular standard 4. The upper end of the sphere 7 is provided with a vent tube 9. The sphere 7 is j acke'ted with another` larger '/hollow sphere of suitable metal concentricwith reference thereto so as to provide a thin continuous water receiving chamber of spherical form between them. The outersphere is comprised of a lower hemisphere 10 supported by a nut 11v threaded on the exterior of the boss 8'- a washer 12 being interposed between the -nut and the hemisphere; and an upper hemisphere 10a secured on the vent .tube 9 by means of a nut 13, a'waslier 14 being provided between it and the said hemisphere.

The opposed edges of the two hemispheres f are'secured by nutted bolts as seen at 15, a

washer 1G being interposed `between said edges. The nuts 1l and 13can be turned toward each other to make the joint of the meeting edges of the hemispheres tight.

17 designates a 'gas burner. This burner is o'f hemispheiical' vform and arranged chiefly 'below the center ofthe inner sphere and it is perforated allover its surface so supply conductor for the burner.

as to direct jets of flame as effectively and as equally as practicable with such construction toward'a large portion of the interior` of the inner sphere. The burner is provided with a tube 17a and mixer 17". The burner. 17 is supplied with fuel- -gas through a pipe 1,8 passed through the tubular'standard and terminating in the mixer 17 b and at a plane opposite the lateral openings 'of the tubular o enings of the tubular standard and below '-t ie burner tube so that air shall be mixed with the gas to insure its effective combastion. l .A

lil-'designates a nipple for connecting a flexible hose to supply gas.

connected with the upper portionfof he' device and" 21 a hot water dischargeconnected with the lower portion of the device, the lat ter providedwith a valve at 22 to control the discharge of' heated water.

In addition to being a quick heater the device can be readily taken apart for clearing it of incrustation precipitated from the water. The device as shown itsl portable but it can be installed as a fixture. With such a device it is not necessary to maintain a iire to keep a ready supply of hot water as water can be suiiciently heated as'it flows through the device from the cold water supply to the discharge, the temperature of the water obtainedbeing regulated by the heat supplied at the burner.

WVhatI claim is:

1. A water heater comprising, in combisov 20- designates a cold water pipe nation, twv spheres of thin sheet-like metal arranged one concentrically within the othei to form a thin sheet like water chamber lictween them, tubular bosses connecting said metallic spheres and forming air passages -into and out of the inner sphere, a' gas burner located within the interior of the inner metallic sphere so as to bc surrounded Yat the sides and above and below by the water chamber, water supply and discharge conductorsior the water chamber, and a gas 2. A water heater comprising, in combination, two spheres of thin sheet-like metal arranged one concentrically within the other to form a thin sheet-like water chamber bevtween them, tubular bosses connecting said chamber, and a gas supply conductor for the metallic spheres and forming air passages burma?. into and out of the inner sphere, avhcmif spherical -gas burner in the interior .of the 5 inner metallic sphere surrounded above and lrVtnesses:

below by the Water chamber, Water supply BENJ. FINQK'EL, and discharge conductorsV for the Water MAYME EGARD.
